The Ramtron FM24W256-EG is a 256-kilobit nonvolatile Ferroelectric RAM (F-RAM) memory. It is organized as 32,768 x 8 bits and utilizes a fast two-wire serial interface with a maximum bus frequency of 1 MHz. This F-RAM offers high endurance with 100 trillion read/write cycles and 38 years of data retention at +75°C.
Designed for wide voltage operation from 2.7V to 5.5V, the FM24W256-EG consumes low power, with an active current of 100 µA at 100 kHz and a typical standby current of 15 µA. It operates within an industrial temperature range of -40°C to +85°C.
The device performs write operations at bus speed with no write delays, allowing the next bus cycle to commence immediately. This makes it suitable for applications requiring frequent or rapid writes, such as data collection or industrial controls. The FM24W256-EG is available in an 8-pin SOIC package and is a direct hardware replacement for EEPROM devices.
